Comment: Also called party-sapphire. Brings to the table: Green, yellow and blue. Clean and precision cut.Visible but not pushy, always surprising with new tones and hues, always pretty. IMHO such a sapphire should be as expensive as classic pink or blue, though of course it is not, at least not yet. Great fun and long lasting value in untreated sapphire. Will earn many "Hey, what kinda stone is that???". You: "That's a rare untreated sapphire from Australia!" Bang.
